Why do wind power, offshore engineering, and heavy equipment manufacturers choose DONGS machine tools?
As the manufacturing industry moves towards high-end development, the equipment structures in heavy industries such as wind power, offshore engineering, and construction machinery are becoming larger and more complex. The common requirements of these industries are: large-size parts, high-strength structures, reliability and consistency under harsh working conditions. In this context, traditional general-purpose machine tools are no longer competent, and the equipment that can truly "hold up, cut, and do things accurately" is the "hard power" in the eyes of customers.
As a result, a company focusing on the research and development and manufacturing of medium and large CNC machine tools has gradually come into the vision of these leading companies in the industry - Shandong DONGS CNC Equipment Co., Ltd.
From wind turbine main shafts to offshore pipe fittings, from hydraulic cylinders to oversized flanges, why are DONGS equipment increasingly appearing in the production lines of these demanding customers? Today, we will reveal the answer.
一、Wind power industry: large size, high precision, tight schedule, DONGS can handle it with ease
The core components of wind power equipment, such as the main shaft, hub, flange ring, etc., are mostly extra-large diameter, long-axis or thick-walled components, which place extremely high demands on the equipment's through-hole capacity, bed rigidity and processing rhythm.
The medium and large horizontal turning centers launched by DONGS have the following capabilities:
Large through-hole spindle (supports diameters over 300mm),Adapt to the smooth penetration of extra-long spindle parts;
Integral casting bed + widened guide rail structure,Effectively resist resonance and deformation during heavy cutting;
Power turret + end tool module,Multiple processes such as turning, drilling and tapping can be completed in one clamping.
After a wind power equipment company introduced DONGS equipment, the single-piece processing cycle was shortened by 35%, the dimensional fluctuation was controlled within ±0.03mm, and it successfully passed the acceptance of German customers.
二、Offshore manufacturing: complex working conditions, diverse materials, one machine is better than many
Common structures of marine engineering equipment, such as thick-walled pipes and high-strength alloy connectors, have a wide variety of processing materials and large fluctuations in mechanical properties. They are prone to problems such as tool skipping, surface burns, and dimensional drift, which pose extremely high challenges to the rigidity of the equipment and the system's responsiveness.
DONGS solutions is to optimize the system in four dimensions: structure, control, cooling and clamping:
Spindle low speed high torque drive,Easily handle large-cutting depth roughing;
Real-time spindle load monitoring,Combined with the cutting path optimization system, intelligently adjust the processing parameters;
Customized hydraulic clamp + tailstock support + heavy-duty tool rest,Ensure stable positioning of complex geometric parts;
Multi-channel chip discharge system,Solve the problem of difficult chip removal of marine engineering alloy materials.
These designs not only improve the processing quality, but also reduce the dependence on operator experience, achieving stable output of "equipment replacing people".
三、Heavy machinery industry: Multiple processes and multiple batches? DONGS composite processing solves all problems at once
In the field of heavy engineering machinery, parts such as hydraulic cylinders, drive shafts, and support arms are not only complex in structure, but also often involve a large number of different hole positions and assembly surfaces. The difficulty in processing lies in "multiple positioning and consistent precision."
DONGS uses a composite processing machine to complete multi-faceted processing in one clamping, effectively avoiding the problem of error superposition. The equipment has:
Power turret and automatic tool change system (ATC),Support fast switching of complex paths;
Digital coordinate compensation system,Solve the accuracy drift caused by thermal deformation;
A heavy equipment company reported: "In the past, three machines were needed to make a porous support part. Now, only one machine can do it with DONGS. The processing cycle has increased by 50% and the number of operators has been reduced by half."
四、Why was DONGS chosen? Not just a “machine”, but also a “system”
Before using DONGS for the first time, many customers thought it was just a "machine tool supplier"; but after in-depth cooperation, they generally reported that DONGS was more like a "process partner."
DONGS insists on starting from the customer's parts, participating in the early process analysis, fixture design, station layout, program optimization, and even the full process solution customization of after-sales maintenance mechanism, forming a complete "equipment + process + service closed loop".This is the real reason why DONGS can enter the demanding industries such as wind power, offshore engineering, and heavy equipment.
Wind turbine main shafts are getting longer and longer, marine engineering materials are becoming more and more difficult to process, and the structures of heavy equipment are becoming more and more complex. Manufacturing companies need not only "big machine tools", but a complete set of "large, stable, strong and accurate" processing systems.
DONGS is becoming the first choice of more and more leading companies with its professional medium and large-scale CNC equipment manufacturing capabilities, practical process integration capabilities, and customer-oriented service concept.
In the future, no matter how difficult the workpiece is or how changeable the scenario is, DONGS will continue to build reliable equipment and trusted systems to provide solid support for the "heavy battlefield" of China's manufacturing.
